Which of the following is a cyanophage?
LPP−1 was the first cyanophage, which was discovered by Safferman and Morris. It was so named because it can infect three different blue- green algae, which are Lyngbya, Pnormidium and Plectonema.
What do u mean by cyanophage?
Cyanophage. A virus that infects a cyanobacterium. Lysogen. A bacterium which has a temperate virus integrated into its genome.
Where are cyanophages found?
The cyanophages are a group of DNA viruses that attack host organisms found within the cyanobacteria or blue-green algae, a group of oxygenic photosynthetic procaryotes.
Who discovered cyanophages?
Solution : Cyanophages were discovered by Shafferman and Morris. Step by step video & image solution for [object Object] by Biology experts to help you in doubts & scoring excellent marks in Class 11 exams.
Which virus has both DNA and RNA?
Leuko virus
Leuko virus is a retrovirus also called as RNA-DNA virus. These virus possess reverse transcriptase. This enzyme builds DNA over RNA genome.
What is the protein coat of a virus called?
protein capsid
The protein capsid provides the second major criterion for the classification of viruses. The capsid surrounds the virus and is composed of a finite number of protein subunits known as capsomeres, which usually associate with, or are found close to, the virion nucleic acid.
How do cyanophages reproduce?
They are all double-stranded DNA viruses. Similar to bacteriophages infecting heterotrophic bacteria, the life cycle of cyanophages consists of adsorption to a host cell and replication, formation, and eventually release of mature progeny phages after lysis of the infected host cells.
Is polio a DNA virus?
Poliovirus is composed of an RNA genome and a protein capsid. The genome is a single-stranded positive-sense RNA (+ssRNA) genome that is about 7500 nucleotides long….
| Poliovirus | |
|---|---|
| Family: | Picornaviridae |
| Genus: | Enterovirus |
| Species: | Enterovirus C |
| Virus: | Poliovirus |
Is chickenpox a DNA or RNA virus?
Varicella-Zoster Virus (VZV) VZV is a DNA virus and is a member of the herpesvirus group. Like other herpesviruses, VZV persists in the body as a latent infection after the primary (first) infection; VZV persists in sensory nerve ganglia.
Does Cyanophage contain both RNA and DNA?
A) Cyanophage: Cyanophage belongs to three recognized families of double-stranded DNA viruses. They have a complex pattern of host ranges, are widely distributed, and can be readily isolated from marine and freshwaters. Thus this option cannot be correct as it contains only DNA.
Is the influenza virus DNA or RNA?
-stranded RNA
All influenza viruses consist of single-stranded RNA as opposed to dual-stranded DNA. The RNA genes of influenza viruses are made up of chains of nucleotides that are bonded together and coded by the letters A, C, G and U, which stand for adenine, cytosine, guanine, and uracil, respectively.
